The invention provides a battery remaining capacity determination method and device, electronic equipment and a vehicle, and can control a power battery to discharge according to a required target remaining capacity if the required target remaining capacity is less than or equal to an original target remaining capacity on the premise of allowing the power correction of the power battery. And the residual electric quantity is corrected according to a preset electric quantity change rate. The power battery is controlled to discharge according to the required target remaining power, so that the power battery is separated from the voltage platform interval, the remaining power is corrected according to the preset power change rate by actively creating the working condition meeting the remaining power correction, the accumulative error of the power battery is reduced, and the power battery quality is improved. Therefore, the vehicle can display the real capacity of the power battery, the accuracy of the endurance of the vehicle is ensured, the power battery is prevented from being excessively discharged or triggering the minimum voltage protection of the battery, the vehicle stall is further avoided, and the driving safety is ensured.

    本申请提供一种电池剩余电量的确定方法、装置、电子设备及车辆,能够在允许进行动力电池的电量修正的前提下,如果需求目标剩余电量小于等于原始目标剩余电量,根据需求目标剩余电量控制动力电池进行放电,并根据预设的电量变化速率进行剩余电量修正。根据需求目标剩余电量控制动力电池进行放电,使得动力电池的脱离电压平台区间,通过主动创造符合剩余电量修正的工况来实现根据预设的电量变化速率进行剩余电量修正,减小动力电池的累积误差,使车辆可以正显示动力电池的真实容量,保证车辆续航的准确性,避免了动力电池过渡放电或触发电池最低电压保护,进而避免了车辆失速,保证了驾驶安全。
